Pull workqueue fix from Tejun Heo:
 "Just one patch to revert commit ca10d851 ("workqueue: Override
  implicit ordered attribute in workqueue_apply_unbound_cpumask()").

  This commit could break ordering guarantees for ordered workqueues.
  The problem that the commit tried to resolve partially - making
  ordered workqueues follow unbound cpumask - is fully solved in
  wq/for-6.9 branch"
